Gonna replace my cats this week, figure the increased mpg will pay for the job eventually. Considering also replacing the stock mufflers (351w w/ dual exhaust). Visually mine are in great shape. I like how they sound, real low and mellow, but Id replace them if it would see my some gains in mpg and/ or perf. Like to keep the same sound if I did replace them.

If they are stock, going to any aftermarket muffler with a decent internal diameter muffler will net big gains. Stock mufflers are like 1-1.5" inside diameter. Just upgrading my single exhaust with a flowmaster made an insane difference.Builder/Owner of Badass Panther Wagons

Word. Hope I can fit new mufflers into the budget too.

Thrush turbos are also cheap, and look a hell of a lot like my Summit mufflers. I wouldn't be surprised if they're the same.86 Lincoln Town Car (Galactica).

Had my new cats put in by some guys my mech. recommended, they weren't the cheapest but they were the closest and do some high quality work (custom shit for expensive new cars). World o' diff. Anywho Id really like some mufflers that are higher flowing than stock.Last edited by 91 LTD; 10-25-2006, 10:32 PM.

I love the deep rumbling muscle car sound my Flowmaster Super 40's put out.They go for $79.99 a piece for the 2 1/2in. Super 40's at jegs.com,which is where I got mine from.My car was originally single exhaust,So I deceided to do all the exhaust work myself from the cats on back and weld all the connections myself,which saved me about $250 over going to the exhaust shop.Last edited by LTDMan83; 10-27-2006, 05:56 AM.Comment

Nice car Custom 87. I wish I had the workspace to do shit like this myself. How do the Flowmasters flow compared to stock? Am really leaning towards some 50s.

Nice ride C87 and nice work on your exhaust swap, you must have seen a huge improvement in performance. I just wish I had the workspace do shit like this myself. Personally, I really liked the sonund of the 50s. My quastion now is how do Flowmasters flow compared to stock what with all the baffles inside them?
